In carrylng out my mvention, may obviousl house the same in any suitablecab inet, at I preferably employ the cabinet 1 shown, which comprisesthe'u per compartment 2, formed by-the lower orizontal shelf 3, the rearwall 4, the fixed top 5, and the front .upper doors 6,,the' latter b inreticulated or consisting of '11s, having, i

rfipresents a vertical section on the radio circuit is o the radiochamber, formed between the partition or shelf 3 already described, andthe shelf 22 below, the front of said radio chamber being closed by thedrop door 23, hinged at the points 24. Be-

,hind the drop door is the control panel 25,

of the coordinating unit, which is preferably ositioned at the rightofthe radio chamer,as will be understood from Fi re 2, the left handportion of the radio 0 amber 21 being The rig it hand coordinatingvunit,carried by the control panel 25, consists of the rheostat 27, having thecontrol'knob 28 which controls the volume of electrically reproducedsounds of the phonograph. On the coordinating unit panel 25, there isalso mounted the operating knob or handle, 29 of the switch orcontacting device 59, which in its extreme positions controls thecircuit of the phonograph or the radio. In the B5 resent construction,when the switch handle is thrown to the left, as seen in Figure 2, totheradio indicia 30, the ra'dio circuit is closed and the radioreceiving 'set is functioning. When the switch handle 29 is 00 thrown tothe right of the position seen in Figure 2, to the phonogra h indicia31, n'and t e phone aph circuit is closed, set at the electrical pcmgraph reproducer is functioning; it being understood that the loud seaker 11 is comcircuits, and the ma er of opening and closing thecircuit 0 each being apparent mon to both the radiiurm the phonographfrom the wiring diagram seenin Figure 9.

The lower compartment formed between the bottom 33 and the upper shelf22, is divided by the central vertical partition 32, into the left andright hand compartments 34'and 35, adapted for the batteries 36 and v 37and record albums 38. The compartments 34 and 35 are closed by the doors39 and 40.

In the constructions seen in Figures 5 and d 6, I have shown the righthand top portion or-lid 41, hin ed at the points 42, and the loudspeakeresi ated as 43, is hinged at the points 44 to 't e under side of saidlid.

which is adapted to stand vertical when the phonogra h or radio isfunctioning, said oud spe er being common to both, as in theconstruction already described. The left hand top portion 45, seen inFigure 5, isprefera lv stationa or fixed.

be The electrical'coordinatmgunit, mounted upon the anal 25, is com sedof the induction coil or transformer 50, havin the grimar coil 51 and asecondary cm 52. ne si e oftheprimary coil 51 is connected throughsuitable connections 53 to one of 2 the two binding posts or lugcontacts 54 adapted to receive the lea '-W116S from thehonographreproducer; the other of said inding osts or plug contacts 55 beingconnected irectly to one side of the storage provided with the radiopanel 26. 75

The coordinating unit'includes te multiple switch or contacting device 59, having the three stationarycontacts 60, 61 and 62 and having the two movable spring contacts 63 and64 which are moved in unison by an insulatin roller 65. carried by thehandle 29 pivote at 66. The movable contact 63 is juxtaposed to saidstationary contact 60, while the movable con.

The second stationary contact 61 is connecteddirectly to 'one side ofthe secondary windi 52 of said induction coil. 50 throu h a saidsecondary windin being connected dir'ectly to one 'of the and speakerbinding i 17 'moving the handle 29 in the direction of the arrow 71,there will also be established.

Thus, upon acomplete electrical circuit through the loud speaker contacts or binding7 3and 7 5 andthe secondary. winding 52,-thro'ugh said stationaryandmovable contacts 61 and 64 respectively, thereby effecting an orative electrical connection from the reco repro-a .ducer to the loudspeaker, in the extrem right hand position of the handle 29.

' One of the bindingposts 77 to which the input line of a radio set isconnected, is di- 7 ing post 73, through the connection78, while thesecond radio in ut bindin post 79 is conhectsd through t econnection 80to the; stationary contact Thus, upon turning the handle in thedirection of the arrow 81,

the movable spring contact 64 will engage,

and make. electrical contact, with the stationar contact 62, therebyconnecting said secon' second loud spea er binding post 75, thereb radioinput binding post with the o ratively connecting. the radio set wit i te loud speaker; while the honograph reproducer is disconnected. bus, thecontacting device 59 has the function of electrically connectingfinseries with each other the record reprodu'cer, the source of electricalenergy, the .rheostat and the primary winding of the transformer; aswell as to connect in series with each other the loud speaker and thesecondary winding of the transformer; of connecting in series, in theopposed extreme position of the handle 29,

the radio set and said loud speaker; and to maintain each of these.elements electrically disconnected, in the intermediate or neutralposition of said handle. These functions are carried out by the vtwoopposed movable. spring contacts 63fand 64, which are constantly urgedtowards each other, by the resiliency thereof, and the separating roller65 interposed between said spring members, as shown particularly inFigure 9.

By-my novel construction in a cabinet, as

shown particularly. in Figures 1 and 4, in mounting the cone type erelation to one of inner walls of the chamber 2, there is obtained anovel combination of cone'loud speaker and a tone chamber 2, one wall ofwhich acts as a sound board for said loud speaker, while the other wallssurrounding act-ass tone or resonat- "ing chamber, which directs andamplifies the of speaker in spaced sound emanatin 'from' said loudspeaker.

The grill front oors ermit the sound to be projected out of sai tone orresonating .chamber, with the front thereof closed and with the loudspeaker concealed.

It will be obviousthat the collocation of the radio panel 26, and thecontrol panel 25, as shownin Figure 2, imparts a symmetrical, balancedandpleasing appearanceto the cabinetfront; and 'I' may if desiredconstruct the radio 7 drawer, (as will. understood from Figure 4,) whichcontains the various coacting radio elements, assembled within saiddrawer ggnel 26 as the front of a,

as a unit, so thatto position the radio, it :s-

. only necessary to push in the drawer. In like manner, aswill beunderstood from Fig-' ures 2'-and 7 to .9, the principal controlelements of the panel 25 are mounted directly thereon, so that on' theremoval ofthe panel all the elements thereon or carried thereby .a'rereadil accessible. rectly connected to the loud speaker bind- It willapparent that only the single control member '29 is nry .in order toonographic reproduction, apd

ity to the control lever 29 enables all the manually operable parts tobe compactly assembled in roximity to each other.

While I have shown the radio as being contained in the drawer, so thatthe coacting radio elements can be readily pushed into position or.withdrawn as a unit, it w1ll be. apparent that my invention is notconfined to this precise construction, as any conventhe radio receivingset by the employment of the cone loud speaker 111 tional or standardform of radio receiving set may be employed.

It will further be understood that the disc records emplo ed may havethe sound reprovarious elements, reproduced sounds of a.

maximum volume are produced from the disc record without the use ofvacuum tubes,

and the control of the volume of saidsounds is instantly effected by therheostat 27 and its adjuncts. By. my novel construction I am enabled totransmit any sounds or signals locally. reproduced from the SOUIldrecord having its grooves formed either mechanie cally or electrically,or I can, reproduce signals of any character, such as high frequencysignals received from a distant station by the manual operation of thesmall lever 29. p

It will be apparent that by the elimination of the vacuum tubes or otheramplifying means from the circuit leading to the electrically operatedphonographic reproducer, both the expense and upkeecpof said vacuumtubes is entirely eliminate so that my device can-bc operated at "aminimum of expense. 3 4

It will be evident that the size, "shape. and contour of the cabinet maybe varied according to requirements, but I, referxtoemploy asmallcompact cabinet having substantially the contour shown, since the depthfrom front to rear need be only slightly in excess of the diameter ofthe turn-table 9, as will be apparent from Figures 4 and 6* Bypositioned above the turn-table 10, as will be seen from Figures 2 and.4, a very compact structure is attained, and the overall'height of thecabinet is reduced to a minimum. The panels 26 and 25 are positioned soas to be readily accessible to a sitting operator, and

the reproduced sounds emanating from the loud-speaker are on about alevel with the operators ear, when in a sitting position andtuning inthe radio, as is evident.

It will now be apparent that I have devised a novel and usefulconstruction of combined phonograph and radio and coordinating unittherefor, which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above description,and while I have, in the present instance, shown and described apreferred embodiment thereof which will give in practice satisfactoryand reliable results, itis to be understood that the same is susceptibleof modification in various particulars without departing from the spiritor scope of the-invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Lettcrs Patent is 1.
